Bakso was chosen by 60% of students, Martabak by 20%, Siomay by 15%, and only 5% chose Other.

OK the problem here is that ‘other‘ is rarely used as a noun. Generally it is used as a noun modifier: “other people“, “other things“, etc. In the above example, what is the noun that is being modified by ‘other’? Well, all of the items in the chart belong to a class, or group, and the name of that group is usually given as a label on the chart. In any case we know that Bakso, Martabak, and Siomay are all different kinds of Asian fast food, so we can write:

Bakso was chosen by 60% of students, Martabak by 20%, Siomay by 15%, and only 5% chose other kinds of Asian fast food.

‘Other‘ is used as a noun in sociology, psychology and anthropology to identify and possibly explain ‘something different from us‘, either as individuals or as a society. In these contexts there is a related concept: ‘otherness‘.
